After giving a halt command, the system is normal until it gives the powerdown message, and then there is a dump of error messages.
This is on a 'freek box' -- a rebuilt computer at free geek in Portland OR.
We believe that this problem has to do with a bug in power management.
We are using kernel 2.6.
The attached text file is a parital copy of the system messages that appear after the powerdown message after all other systems have been halted.
Thank you for your time and efforts to maintain the kernel code.
Sincerely,
Shawn Smith
